Liquid electro-photographic printing transfer

A print control apparatus, comprising:

• a processor;
• and
• memory storing instructions which, when executed by the processor, cause the processor to:
• determine a position, a width, and a length of an image to be printed, relative to a direction in which a print medium for receiving the image is fed through a liquid electro-photographic printing system having a binary ink developer assembly including a plurality of members defining a flow path for a printing fluid containing charged particles, the plurality of members including a first member and a second member that are arranged to generate an electric field therebetween, the first member having a plurality of segments,
• correlate the image to one or more of the segments based on the position and the width of the image, and
• determine a timing to activate the one or more segments for printing based on the length of the image.

A print control method, comprising:

• dividing an image to be printed into color separations;
• dividing the color separations into width intervals and length intervals relative to a direction in which a print medium for receiving the image is fed through a liquid electro-photographic printing system having a binary ink developer assembly including a plurality of members defining a flow path for a printing fluid containing charged particles, the plurality of members including a first member and a second member that are arranged to generate an electric field therebetween, the first member having a plurality of segments;
• and
• for each color separation
• identifying one or more segments to activate based on the width intervals corresponding to the color separation, and
• determine activation timing and deactivation timing for the one or more segments based on the length intervals corresponding to the color separation.
